A device including: a tubing clamp having a clamping mechanism holding closed a first fluid line while a second fluid flows along a second fluid line from a second container, the first fluid line delivers a flow of a first fluid and a vacuum activated catch retainably coupled with the tubing clamp and coupled with the second fluid line, the vacuum activated catch including: a movable element coupled with the tubing clamp and configured for changing from a first shape to a second shape upon receipt of a deforming pressure, wherein when the movable element is in the first shape, the vacuum activated catch retains the tubing clamp in a closed position, and when the movable element is in the second shape, the vacuum activated catch releases the tubing clamp into an open position, thereby allowing the flow of the first fluid to commence within the first fluid line.
